I ordered a set on line from a E bay seller and received them yesterday for my 2019 Santa Fe SEL.
I installed them today, they fit perfectly. Also they were a breeze to mount, just remove 3 screws from front inner wheel well and 2 from the back. The guards have holes that line up perfectly with the existing screw holes. I just used the original screws that I removed to mount the new guards.
I can highly recommend them.

 

Good for you.
Another mod that makes it owner happy
Only thing better would be to have parts number
Or, even a picture of the new mud guards.
